Although there is an increasing interest in the development of novel natural nutraceuticals, it is important to ensure their preservation and delivery by their encapsulation, a technology that is gaining popularity in the food industry. The encapsulation of selected nutraceuticals, including enzymatically-synthesized phenolic lipids and self-assembly polymers of proteins and polysaccharides, was carried out. Our research group succeeded in the production of novel biomolecules of high nutritional value and antioxidant capacity, phenolic lipids (PLs), by a biotechnological process involving the esterification of selected phenolic acid models and endogenous edible oils. The encapsulation of PLs was carried out by the development of a process to yield gelatin-gum Arabic multinuclear microcapsules, via complex coacervation. The overall experimental findings indicated that the microencapsulation of PLs was effective for preventing their oxidation and hence by maintaining their antioxidant potential. On the other hand, the self-assembly of selected proteins (patatin and lysozyme)/polysaccharides (galactan, gum Arabic and xanthan gum)-based nanoparticles was investigated. The results indicated that the nanoparticles have spherical shape and their sizes were dependant on the pH and the molar ratio of protein to polysaccharide. Through the zeta (ζ) potential measurements, the formation mechanism of amphoteric patatin/xanthan gum and lysozyme/galactan nanoparticles was illustrated.
